Remarks

This class represents an Internet Protocol version 4 (IPv4) address. Defined by RFC&nbsp;790: Assigned Numbershttp://www.ietf.org/rfc/rfc790.txt, RFC&nbsp;1918: Address Allocation for Private Internetshttp://www.ietf.org/rfc/rfc1918.txt, and RFC&nbsp;2365: Administratively Scoped IP Multicasthttp://www.ietf.org/rfc/rfc2365.txt<h3> "format">Textual representation of IP addresses</h3>

Textual representation of IPv4 address used as input to methods takes one of the following forms:

<blockquote><ul style="list-style-type:none"> <li>d.d.d.d</li> <li>d.d.d</li> <li>d.d</li> <li>d</li> </ul></blockquote>

When four parts are specified, each is interpreted as a byte of data and assigned, from left to right, to the four bytes of an IPv4 address.

When a three part address is specified, the last part is interpreted as a 16-bit quantity and placed in the right most two bytes of the network address. This makes the three part address format convenient for specifying Class B net- work addresses as 128.net.host.

When a two part address is supplied, the last part is interpreted as a 24-bit quantity and placed in the right most three bytes of the network address. This makes the two part address format convenient for specifying Class A network addresses as net.host.

When only one part is given, the value is stored directly in the network address without any byte rearrangement.

For methods that return a textual representation as output value, the first form, i.e. a dotted-quad string, is used.

<h4> The Scope of a Multicast Address </h4>

Historically the IPv4 TTL field in the IP header has doubled as a multicast scope field: a TTL of 0 means node-local, 1 means link-local, up through 32 means site-local, up through 64 means region-local, up through 128 means continent-local, and up through 255 are global. However, the administrative scoping is preferred. Please refer to RFC&nbsp;2365: Administratively Scoped IP Multicasthttp://www.ietf.org/rfc/rfc2365.txt
